Quick follow up:
Yesterday we installed the new front brake lines.
Today we are starting with the buiding of the exhaust. It's going to be a two stage design with a box type collector under the gearbox. This contains perforated sheet metal for creating back pressure. Out of this box comes a 54 mm to +/- 120 mm megaphone type muffler with a perforated pipe and stainless steel wool interior. Of course the muffler ends with a reverse cone made from billet on a lathe.
My brother consulted a gas flow technician and he said that this could work very well. We use 0,7 mm. ss sheet material for the box and the muffler. It seems that a lot of exhaust dB's originate from resonating sheet material.
Adding a db-killer is also going to be possible.
And coming friday I can pick up the paintwork! :pic:
The rest of the bike is ready and runs. (that's important too)
Just a quick question: We came up with this solution for fastening tha battery. Because it's a gel battery, this should work. What do you think?
